SMOKING-PIPE. I

- Specification of Letters Patent.

Patented May 22, 1917.

Application filed October 13,1915. Serial No. 55,726.

7 '0 all whom it may concern:

Be it known that I, WALTER H. STRAW, a

citizen of the United States, residing at' Bridgeport, in the county ofFairfield and State of Connecticut, have invented certain new and usefulImprovements in Smoking- Fipes, of which the following is aspecification.

My invention relates to smoking pipes and rfnore particularly to asectional bowl there- The primary object of my invention resides in theprovision of an improved pipe having a bowl composed of two complementalsections provided with means therein for receiving a packing material toprevent leakage and also novel means associated with the ends of thesections for clamping the sections in position.

Another object of my invention resides in the provision of a novel meansfor removable association between the sections for retaining nicotintherein.

A still further object of sides in the provision of my invention readevice of the character described that is simple in con struction,eflicient in operation and one that can be manufactured and placed onthe market at a minimum cost.

Other objects as well as the nature, char- I acteristic features andscope of my invention will be more readily understood from the followingdescription taken in connection with the accompanying drawings andpointed out in the claims forming a part of this specification.

In the drawings:

Figure 1 is a longitudinal sectional view of my invention;

Fig. 2 is a top plan view of the two sections of the bowl spaced fromeach other, the bowl portions proper thereof being shown in section toillustrate the arrangement of the grooves for receiving the packingmaterial;

Fig. 3 is a bottom plan view of the cap for holding the outer ends ofthe bowl sections together;

' Fig. 4 is an enlarged longitudinal sectional view of the cylindricalframe for supporting the absorbent material for retaining the nicotin;and

Fig. 5 is a bottom plan view of the cap for gether.

longitudinal recesses I Referring more particularly to the draw- 1ng sin which similar reference numerals designate like or correspondingparts throughout the difi'erent views, I provide a pipe'includinga bowlcomposed of two complemental bowl sections 1. These two sections areeach provided on their inner surfaces wlth arcuate recesses 2 which,when the sections are arranged in abutting relation, form atobaccoreceiving chamber. These recesses terminate at their lower ends inlongitudinal grooves 3 which form the smoke chamber, the latterextending at substantially right angles from the bottom of the tobaccochamber. These grooves are enlarged intermediate their ends to provide4, each having curved bottoms to form a substantial cylindrical chamberfor a purpose to be hereinafter described. The sections are furtherprovided on their inner surfaces adjacent their inner and outer edgeswith a straight groove 5 merging with a curved groove 6 which, when thesections are together form chambers which are adapted to receivesuitable packing material 6 to prevent leakage when the sections aresecured together.

In order to removably hold the two sections in position, I have providedan enlarged circular cap 7 for engagement with the upper or outer edgeof the bowl proper. This cap has an annular flange 8 extending from theupper edge thereof which rests upon the upper edge of the sections, theopening 9 provided between the ed es of the flange permitting theplacing o tobacco within the tobacco chamber formed when the outer endof which is removably arranged 100 within a threaded recess 13 providedbetween the sections and communicating with the smoke chamber providedby the grooves 3. The opposite threaded end of the connecting screw isengaged in the correspond- 105 lngly formed recess 14 in a stem 15, thesmoke chamber 16 which extends longitudinally through the stem from themouth iece 17 to the recess is arranged in 9.11m-

ment with the opening inthe threaded (3011- 'necting piece which is inturn 1 arranged in alinement with the smoke chamcan easily be seenincidentally ber formed by the recesses 3 in the bowl sections.

a For the purpose of retaining nicotin in the bowl sections andpreventing it from entering the mouth of the user of the pipe, I haveprovided preferably a closed cylindrical perforated frame 18 havin acover 19 preferably of absorbent materia arranged in closerelationthereabout. Thisnicotin retaining device isremovably arrangedinthe cylindrical chamber formed by the recesses 4 in the bowl sectionsand is illustrated to advantage in Fig. 1 of the accompanying drawings.

The operation of my invention is as follows: When the pipe is assembledas described and as shown in Fig. 1, tobacco is placed within thetobacco receiving chamber formed by the recesses 2 and lighted, thesmoke that is drawn through the smoke chambers in the bowl sections ispurified or rather the nicotin is removed from the smoke, whence itpasses through the opening in the connecting piece and the smoke chamber16 in the stem into the mouth of the user. In cleaning the pipe the caps7 and 10 may be removed after the stem has been removed which permits ofthe sections 1 being taken apart so that they can be cleaned to permitof theremoval of the nicotin retaining device. A new one ofothesedevices may be replaced when the sections are clamped into position.Also the packing 6 within the grooves 5 prevents leakage of smoke ornicotin from the bowl when. it is assembled. I

From the above description taken in connection with the accompanyingdrawings, it that I have provided a device that is simple inconstruction, containing a few simple parts that can be cheaplymanufactured and assembled and It will be understood that the above de-I scription and accompanying drawings com prehend only the preferredembodiment of my invention and that various minor changes in detail ofconstruction, proportion and arrangement of the parts -may be madewithin the scope of the appended claims and without sacrificing any ofthe advantages of my invention.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is 1 1. In a pipe, the combination with thetapered complemental stem sections having semi-circular threadedrecesses communicating with smoke channels, of a tapered ferrule adaptedto engage the tapered ends of the stem. sections when closed, a threadednipple adapted to be screwed into the screw recesses and projectedbeyond the ferrule, and a mouth piece adapted to be screwed on the saidprojecting ends into engagement with the ferrule to cause a clamping ofthe complemental pipe sections together.

2. In a pipe, the combination with the complemental stem sections havingav chamber communicating with smoke channels at each end, of anabsorbent cartridge comprising a rigid body portionhaving an absorbentcovering, said cartridge being adapted to rest in the chamber, a mouthpiece for the pipe, andmeans actuated by the mouth piece for clampingthe complemental pipe sections together and securing the absorbentcartridge in position, said cartridge thereby forming a packing and asmoke filter.

In testimony whereof I aflix my signa ture in presence of two witnesses.
